Every other listing on this shelf is a kit. One is called a set without saying how many units are in the box; one ships three adapters. This one ships one, and says so in its own title: an add-on unit, compatible with all TP-Link powerline adapters.
That is useful in a specific way. Powerline works in sets of two or more — the eighth bullet states it plainly — so a single unit is only ever a third room added to a pair that already works. Buying a second kit to reach a third room wastes an adapter; this is the part that does not. At $23.98 on October 26, 2026 it was the cheapest listing on this shelf by six dollars — but it is one adapter, and powerline needs two.
Two figures on this page appear nowhere among the five published listings here. The second bullet gives AV1000 speeds up to 750 feet — a reach, in feet, over existing wiring. The intro to this section is explicit that the electrical path between two sockets is what settles the outcome, and until now not one listing on this shelf has offered a distance at all. It is a maker’s figure under ideal conditions, like every powerline number, and the same bullet says so: speeds cannot exceed the internet plan’s limit and may be lower for wiring quality, distance and interference.
The second is the fifth bullet, and it is the most concrete warning on this shelf: performance may be limited or blocked in houses with AFCI breakers, which the bullet says are standard in many homes built after 2000. Arc-fault breakers are a code requirement in American and Canadian houses and they filter exactly the kind of high-frequency signal powerline depends on. No published listing on this shelf mentions them. The same bullet adds that powerline may not work with routers or gateways running modified or open-source firmware, naming DD-WRT.
The fourth bullet gives the usual conditions in a clearer form than most: straight into a wall socket, on the same circuit, not through a power strip, a surge protector or an extension lead, and away from washing machines, refrigerators and air conditioners. The intro to this shelf gives the same advice; it is better coming from the maker.
The standard is HomePlug AV2, stated in the second bullet, and the first says the unit is compatible with all TP-Link powerline adapters. AV1000 is 1000 Mbit/s, which the published TP-Link kit on this shelf explains is the theoretical sum of the standard’s peak rates rather than a throughput. One gigabit Ethernet socket, stated in the sixth bullet, with one lead in the box.
There is no pass-through outlet. The kit version of this same adapter has one, rated to 16 A, and that version is on this shelf; the add-on unit does not, so the wall socket it occupies is gone. The tenth bullet states that the unit has no Wi-Fi capability, which is the kind of negative that saves a return.
The ninth bullet gives a power-saving mode reducing consumption by up to 85 per cent, with three asterisks and no footnote on the page to explain them. At 272 g (9.6 oz) and 65 by 52 by 51 mm (2.01 in), the description gives the dimensions in inches as 2 by 1.1 by 2.6 — which multiplied out is 51 by 28 by 66 mm (2.60 in) and does not match the record’s 52 mm (2.05 in) middle figure. The two sets of measurements disagree on one axis.
